It sounds like you're experiencing twitching in your left thumb and have a history of twitching and numbness in other areas. This could be related to several factors, including muscle fatigue, nerve irritation, or even underlying conditions.

Here's a breakdown of what might be happening:

1. Muscle Fatigue or Strain: Frequent use of your thumb or repetitive motions may lead to muscle fatigue, causing twitching when pressure is applied.
2. Nerve Impingement: If you're experiencing numbness in your arms at night, it could indicate nerve compression (like carpal tunnel syndrome) that might also be affecting your thumb.
3. Other Conditions: Conditions such as fibromyalgia or even multiple sclerosis can lead to muscle twitching and spasms.

Next Steps to Consider:

1. Rest and Avoid Overuse: Give your thumb a break from activities that cause discomfort or strain. Limit any repetitive movements for a few days to see if symptoms improve.

2. Cold Compress: Applying a cold compress to your thumb for 10-15 minutes can help reduce inflammation and may alleviate twitching.

3. Gentle Stretching: Perform gentle stretches for your hands and fingers to improve flexibility and reduce tension. Pay attention to stretching your thumb flexors and extensors.

4. Maintain Good Posture: Ensure that when using your hands, you maintain ergonomic positions that reduce strain on your wrist and thumb.

5. Stay Hydrated and Nourished: Sometimes, twitching can be exacerbated by dehydration or electrolyte imbalances. Ensure you're drinking enough fluids and eating a balanced diet.

6. Track Symptoms: Keep a daily journal noting when the twitching worsens or improves, as well as any other symptoms like sleep disturbances. This can help identify patterns and triggers.

Monitor your symptoms closely for any changes. Should the twitching persist or worsen, or if you develop additional symptoms (like weakness or difficulty coordinating movements), consider seeking further evaluation for a more definitive diagnosis.
